EXPLANATION OF NETFLIX’S HUMAN RESOURCES CHARACTERS’ HEIGHTS

We estimated the heights of the characters based on how tall they stand beside their humans and beside each other.

According to World Data, American females stand at an average height of 5 feet and 4 inches. Since Emmy stands about an inch shorter than the human, Becca, in the show pictures, we approximated her to be 5 feet and 3 inches in height.

Next, based on the series stills, Connie looks about a foot taller than Emmy at 6 feet and 3 inches.

Finally, based on Maury and Connie’s picture, Maury stands about an inch taller than Connie at 6 feet and 4 inches.

EXPLANATION OF NETFLIX’S HUMAN RESOURCES CHARACTERS’ AGES

The first episode of the show mentioned Maury’s age

Then, we got Connie’s age from the Big Mouth Fandom Wiki page.

Lastly, we estimated Emmy’s age based on her position in their department while comparing it to the other characters’ ages.

Considering that the characters are million years old and Emmy has a youthful personality, unlike Maury and Connie, we estimated her to be younger than both at around 10 million years old.
